HARDWARE DESCRIPTION
The product, member of the ST19W platform, is a
serial access microcontroller specially designed
for cost effective secure portable applications.
It is manufactured using an advanced highly reliable ST CMOS EEPROM technology.
It is based on the STMicroelectronics 8 bit CPU already implemented o n the ST19X produc t family
and includes on-chip memories: User ROM, User
RAM and EEPROM with state of the art security
featur es. ROM, RAM and EEPROM memo ries can
be configured into partitions with customized access rules .

USER ROM
An additional ST ROM contains all ST provided
functions and libraries.
Access from any memory area to another are protected by hardware FIREWALLS. Access rules are
User defined and can be selected by mask options.
The chip includes a DES accelerator which is accessible via crypt o gr aphi c so ftware libraries located in ST ROM.
As with all the other S T19W products, a serial interface fully compatible with the ISO7816 standard
for Smartcard applications is available.
A CRC calculation block is also available and i s directly accessible by the User.
